We have collected data with a Qualisys motion system ( 4 cameras,Mac Reflex). Our specimen ( Lumbar spine region,cadaveric) were cycled 8 times. We tracked the Data with QTRAC version 2.5

As it is the data is exported to EXCEL. The goal is determine the linear and angular displacement of each marker,(around 15 markers) in 3-dimensions, for each of the 8 cycles. Due to the volume of the data and the mathematical difficulty of calculating 3-dimensional displacements, we were unable to get the desired Data using excel.

Is there a software package to that would allow use to do this analysis, or has some one written a program that we could use for this application. Is there a way of simplifying/condensing this data?
